MULTIPLE BLAST-BURNER.

Specification of Letters Patent.

atented Nov. 7, 1913.

Application filed March 27, 1915. Serial No. 17,383.

To all whom t may concern Be it known that we, Vlfrnnrair W. KEMP and lVILLraM H. VAN HORN, citizens of the United States, residing at Baltimore, State of Maryland, have invented new and useful Improvements in Multiple Blast-Burn ers, of which the following is a specification.

This invention relates to gas burners, and has for an object to provide a multiple blast burner with separate controls for the pilot and blast of each of the separate tips of the burner, said controls being arranged in multiple whereby the pilots of all of the burner tips may be simultaneously controlled, and whereby all of the blastsof the burner tips may be simultaneously controlled.

Another object of this invention is to provide a multiple blast burner with a row of burner tips carried upon a single manifold, and to provide the manifold with two independent passages, one for the pilots of all of ent invention isthat in nearly every use of this burner it is desired to admit the fluid through the separate blast and pilot openings under different velocities to obtain various desired flame effects. The main valve admits fuel to the two parts of the burner, and the secondary valves in the separate passages are adjusted to correctly proportion the velocities of the fluid in the separate passages and to correctly shape the llame to better adapt the burner to its specific use. The main valve is adjusted to control the increase or decrease of the intensity of the heat of the flame of the burner without disturbing the character of the flame, the secondary valves remaining in their initially adjusted position.

A further object of this invention is to provide a multiple blast burner which is of such construction that when supply of gas and air mixture is not available raw gas may be supplied to the pilots and air supplied to the central or blast openings, one valve may be employed for each fluid for all of the burner openings.

'The above and other objects and advantages of this invention will be more thoroughly described and point-ed out in the following detail description of the present embodiment of this invention, the same being shown in the accompanying drawings wherein,-

Figure l is a side elevation of the improved multiple blast burner. Fig. 2 is a detail enlarged longitudinal sectional view of the inner end of the burner. Fig. 3 is a similar view of a slightly modified form of the burner. Fig. a detail enlarged sectional view of one of the burner tips and the adjacent part of the manifold.

Referring to the drawings, and particularly to Figs. 1 and 2, it will be noted that the burner comprises a manifold 10 in the form of a length of pipe having caps 11` closing the opposite ends thereof. Concentric within the manifold 10 is a supply pipe 12, the latter beinO supported in the end caps 11 and having' communication with a gas supply 18. The gas supply 13 may be in the form of an elbow 'casting having a needle or other suitable valve 14; therein for controlling' the passage of gas or air to the supply pipe 12.

As shown to advantage in Figs. 2 and l, the supply pipe 12 has in its side a row of blast tubes 15 radiating from the pipe 12, and passing up into burner tips 16. rlhe tubes 15 terminate in burner disks 17 having small central apertures communicating with the tubes 15 and through which the blast supply issues. The burner disks 17 are provided with radiating slots opening through the edges of the disks and which communiabout the pipe 15. The burner tips 16 are "preferably cylindrical in form and are secured at their inner ends through the wall of the manifold 10, and communicate with the interior of the manifold through annular openings 18 formed about the blast tubes 15.

The manifold 10 is supplied with gas through a pipe 19 having in one portion thereof a needle or other suitable valve 20 to control the passage of the gas into the manifold. As shown in Figs. 1 and 2, the pipes 13 and 19 communicate with a single main gas supply 21, the latter being arranged between the valves 1li and 20, and adapted to supply gas not only to the manifold 10 but also to the blast pipe 12. The

under pressure and being controlled by aV 40 to the burners.

Y of the can making machine, and the Weight of the tin plate used vary, the valve 25 may be adjusted to increase or decreasel the 1ntensityV of the heat of the flame Without disturbing the valves 14 and 20 or the shape of the flame. lt Will be noted that by this arrangementy the valve 14 simultaneously lcontrols the flovv of'gas through all of the tubes 15 of the various burner tips 16 While the valve 2O simultaneously controls the flow of gas through the slots of all of the burner disks 17 of` the various burner tips 16. The entire line of flame of thelmultiple I burner can thus be controlled to secure the desired blast and the desired volume of flame.

Vln the modified construction, shown in Fig, f8, the manifold 10L has at one end a nipple or cap 22 for connection with a gas supply pipervvhich is provided With a suitable Vvalve 23V controlling the volume of said gas passing through the supply pipe. The blast supply pipe 12a, which is concentric Within the manifold "10a, passes through the end of the nipple or cap 22, as in the preferred form, and has connection Withga-n air `supply pipe, the air being valve 24. Y

The Vsupply pipe 12a feeds the airV to the center blast of the row of burner tips, While they manifold 10a feeds the gas to the pilot of the burner tips,'and the arrangement ofV the single valve for the pilot, admits of the simultaneous control of the blasts of all of Ythe burner tips independently of the simultaneousfcontrol ofthe pilots of all of the burner tips.

Although the above; describes 'the' p-referredembodimen't of the invention,'it is to be understood that it is Within the spirit of the invention to make various Vdetail changes in the constructionand arrangement of the parts of the burner Within the scope ofthe following claims. Y

What isclaimed is- 1. In a multiple blast burner,l a plurality of tips, each having a blast and a pilot opening, a valve controlling the blast openings of all of said tips, arsecond valve controlling the pilot openings of all Vof said tips, a single main supply pipe supplying a gas to both of said valves, and a main valve controlling the fion7 of gasthrough the main supply pipe. Y

Y2. Tn' a. multiple blastV burner, a manifold, a supply pipe Within the manifold,a

plurality of burner tips or casings mounted Yon the manifold and communicating there with, a burner-tubewithin each of saidV tips and communicating Withthe supply pipe, a` Y burner plug in each Vof said tips at a distance below7 the upper end thereof and having a small central aperture communicating With said tubes and throughY which the blast supply issues, said plugsV also having opens inOs communicating throughV said tipsWith thermanifold to provide pilot openings, aV valve for said supply pipeV for controllingY the blast openings ofl all of said tips,"an`d' a, second independent valve forpsaid manifold for controlling the pilot openings of all of saidtips.'V Y ln testimony whereof Wer have hereunto set o'urphands in presence'of-tivo subscribing s y Witnesses.
